Ujiji is a historic town on Tanzania's Lake Tanganyika shore, about 6 km south-east of Kigoma.

Where it is

Ujiji is on the eastern shore of Lake Tanganyika, in its northern third (110 mi south of the lake's northern tip).

Shore, third and distances are measured from the coordinates above against the lake’s mapped outline.

The water

Lake-wide measured chemistry of Lake Tanganyika — collection points share their lake's water; site-specific figures are shown only where the literature records them.

Surface temperature here

Across May–Oct, monthly means run 78 °F to 80 °F — coolest in Aug. Measured by satellite 1995–2023: the daily median of clear readings within 10 km of the site (645 clear days). The rainy-season months are usually too cloudy to measure and are left blank.

Each entry below is the population of that species recorded here — the form aquarists keep and breed as a distinct, provenance-labelled line. Crossing forms from different collection points is considered hybridisation in the hobby.
